Summer in Chaitén

Chaitén in summer is a gateway to Pumalín Park's ancient alerce forests, volcanic landscapes, and pristine hot springs. This resilient town on the Carretera Austral offers raw Patagonian wilderness, excellent fishing, and ferry connections to Chiloé.

Chaitén, a small town on the shores of the Gulf of Corcovado in Chile's Los Lagos region, is a destination defined by resilience and raw natural beauty. Nearly destroyed by the eruption of Chaitén Volcano in 2008, the town has been rebuilt and now serves as the northern gateway to the Carretera Austral and the magnificent Pumalín Douglas Tompkins National Park.

Summer from December to February is the best time to explore this region, when the dense temperate rainforests are lush and green, rivers run clear for fishing, and the weather is at its most cooperative. Pumalín Park, one of Chile's largest protected areas, shelters ancient alerce trees (some over 3,000 years old), pristine fjords, and volcanic hot springs.

The ghost town section of old Chaitén, partially buried under volcanic mud, stands as a haunting reminder of nature's power and has become an attraction in its own right. Meanwhile, the rebuilt town offers ferry connections to Chiloé and serves as a supply point for Carretera Austral travelers.

Summer visitors can enjoy hiking through old-growth forests, soaking in natural hot springs, fishing the renowned Yelcho River for trout and salmon, and exploring the volcanic caldera. The combination of volcanic drama, rainforest beauty, and maritime Patagonian culture makes Chaitén a compelling summer destination.

Pricing

Chaitén is moderately priced. Accommodation is affordable compared to southern Patagonian destinations. Park entrance is free as a national park. Fishing guides are the main premium expense. Ferry tickets should be booked well in advance for vehicle transport.

Driving Conditions
